Rotary Cutter Blade Offset CCW Lift fits Bush Hog SQ7 SQ840 277 287 220 2620 1251210 fits Land Pride RCR3515 820-138C fits John Deere WP7557

What It Is

This is a heavy-duty rotary cutter blade designed for offset, counter-clockwise (CCW) lift applications. It fits Bush Hog SQ7, SQ840, 277, 287, 220, 2620, and 1251210 models, plus Land Pride RCR3515 (OEM 820-138C) and John Deere WP7557. It’s used for medium-to-heavy brush and grass cutting on finish or rough-cut mowers.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size: This blade fits 60–72-inch decks on the listed models. Measure your current blade length (typically 26–30 inches) and ensure it matches.
• Mounting hole: Check that your spindle uses a 1-inch center hole with a 5/8-inch offset (common for Bush Hog and Land Pride). Measure your spindle bolt pattern—some John Deere decks may require a different offset.
• OEM cross-reference: This aftermarket blade replaces Bush Hog 1251210, Land Pride 820-138C, and John Deere WP7557. Verify your model’s OEM part number against this list. If your blade has a different OEM number, it likely won’t fit.

Key Things to Know

• Quality: Made from heat-treated, high-carbon steel—holds an edge longer than standard blades but may be harder to sharpen. Rated 5.0/5 (1 review) but limited feedback.
• Installation difficulty: Moderate. You’ll need a torque wrench (specs usually 80–100 ft-lbs for these spindles) and a blade puller if rusted. Always replace blades in sets for balance.
• Lift direction: This is a CCW (counter-clockwise) lift blade—ensures proper grass/brush discharge. Installing it backwards on a clockwise spindle will cause poor cutting and vibration.
• Common gotcha: These blades are thicker (0.25–0.31 inches) than standard finish blades. Check your spindle’s blade-mounting clearance—some older decks may need shorter bolts.

Should You Buy It

Buy this if you own a Bush Hog SQ7/SQ840, Land Pride RCR3515, or John Deere WP7557 and need a rugged, direct-replacement blade for heavy brush. It’s a solid value at $86.94 for a heat-treated aftermarket option, but with only one review, verify fitment carefully—especially if your deck is pre-2000 or has non-standard spindles. Not ideal for light residential mowing; it’s built for commercial or acreage use.
